Jeff,

I have one of those MV-1B boards that is for the Irritating Maze only (it's got that Saurus bios). From discussion on the other boards here, I realize there is a fix for that. How much would it cost to do this?

I can wire a socket on it to put a DIP style rom in, which I would then put in a normal 1-slot bios -- this is what I just did for a guy named Mike who got a 1B from NGF (sold to him as a *normal* MVS unit.

I was unable to locate an SOP style eprom (not even from SNK!!), so I couldn't do an exact chip replacement.

Hopefully in the near future someone will be able to supply me with a couple eproms that are the right size, then there will be no need to wire in a socket.

I charged Mike $25 to do the work, plus $7 return shipping.

Try Oki

For the P2ROM, you have to have Oki program the device for you (but they claim it it no extra cost).

Sounds good, Jeff. I'm thinking about boxing up the board to send to you sometime next week.

I've noticed that the Saurus bios won't let you enter your initials correctly for high scores on some games (Blazing Star)- and I've heard certain other games won't be playable with it.

Thanks for the lead SmokeYa, but they don't have the right part.

Jeff,

Let me know the specs for the part and I will keep looking.
